Patent number: 8074231Abstract: In some implementations, the operations of a software system may include the execution of untrusted device drivers. The execution of an untrusted device driver may be initiated when an untrusted device driver that is a set of executable instructions is obtained. A computing resource for the execution of the device driver may be further determined from a device-driver manifest of the untrusted device driver. Computing resources may include one or more of a hardware resource, a memory, an input/output port, an interrupt request line, and an inter-process communication channel. Trusted local access objects may be used by the untrusted device driver to access the computing resources.Type: GrantFiled: June 30, 2006Date of Patent: December 6, 2011Assignee: Microsoft CorporationInventors: Galen C. Hunt, James R. Larus, Manuel A Fähndrich, Orion Hodson, David R. Tarditi, Michael Spear, Michael Carbin, Steven P. Levi, Bjame Steensgaard

Publication number: 20100287271Abstract: A controller, referred to as the “BMonitor”, is situated on a computer. The BMonitor includes a plurality of filters that identify where data can be sent to and/or received from, such as another node in a co-location facility or a client computer coupled to the computer via the Internet. The BMonitor further receives and implements requests from external sources regarding the management of software components executing on the computer, allowing such external sources to initiate, terminate, debug, etc. software components on the computer. Additionally, the BMonitor operates as a trusted third party mediating interaction among multiple external sources managing the computer.Type: ApplicationFiled: July 19, 2010Publication date: November 11, 2010Applicant: Microsoft CorporationInventors: Bassam Tabbara, Galen C.

Patent number: 7739380Abstract: A multi-tiered server management architecture is employed including an application development tier, an application operations tier, and a cluster operations tier. In the application development tier, applications are developed for execution on one or more server computers. In the application operations tier, execution of the applications is managed and sub-boundaries within a cluster of servers can be established. In the cluster operations tier, operation of the server computers is managed without concern for what applications are executing on the one or more server computers and boundaries between clusters of servers can be established. The multi-tiered server management architecture can also be employed in co-location facilities where clusters of servers are leased to tenants, with the tenants implementing the application operations tier and the facility owner (or operator) implementing the cluster operations tier.Type: GrantFiled: November 12, 2004Date of Patent: June 15, 2010Assignee: Microsoft CorporationInventors: Galen C.

Patent number: 7668906Abstract: A wire protocol provides message formats for creating multiple network connections between a media server and a client. These multiple network connections may include a control link connection for passing control information and a data funnel connection for passing data of multiple media. The data funnel connection may be a multipoint-to-point connection that connects multiple data servers with the client. The protocol facilitates multiple requests being concurrently outstanding and asynchronous processing of requests. The protocol is designed to exist on top of a transport protocol layer.Type: GrantFiled: November 20, 2007Date of Patent: February 23, 2010Assignee: Microsoft CorporationInventors: William J. Bolosky, Craig M Dowell, Robert P. Fitzgerald, Steven P. Levi, Jan de Rie, Richard F. Rashid

Patent number: 7466721Abstract: An active stream format is defined and adopted for a logical structure that encapsulates multiple data streams. The data streams may be of different media. The data of the data streams is partitioned into packets that are suitable for transmission over a transport medium. The packets may include error correcting information. The packets may also include clock licenses for dictating the advancement of a clock when the data streams are rendered. The format of ASF facilitates flexibility and choice of packet size and in specifying maximum bit rate at which data may be rendered. Error concealment strategies may be employed in the packetization of data to distribute portions of samples to multiple packets. Property information may be replicated and stored in separate packets to enhance its error tolerance. The format facilitates dynamic definition of media types and the packetization of data in such dynamically defined data types within the format.Type: GrantFiled: October 28, 2004Date of Patent: December 16, 2008Assignee: Microsoft CorporationInventors: Steven P.

Patent number: 7395320Abstract: Enforcing policy in a multi-computer service application is described. In one aspect, a scale-independent logical model of an application is generated. The application is for implementation in a distributed computing system. The scale-independent logical model includes multiple components representing logical functions of the application and intercommunication protocols. The model components are converted into one or more instances representative of physical resources used to implement the logical functions. The instances specify information such as communication ports on the physical resources and communication paths that link the physical resources.Type: GrantFiled: June 1, 2005Date of Patent: July 1, 2008Assignee: Microsoft CorporationInventors: Galen C.

Patent number: 7155380Abstract: A system facilitates the design and implementation of large-scale applications, such as Internet Services and Websites, for distributed computer systems, such as server data centers, Internet data centers (IDCs), Web farms, and the like. The system has a modeling system and a deployment system. The modeling system permits developers to architect the hardware and software used to implement the applications in an abstract manner. The modeling system defines a set of components used to describe the functionality of an application. The model components are arranged and interconnected to form a scale-independent logical model of the application. Once a logical model is created, the deployment system uses the logical model to automatically deploy various computer/software resources to implement the application. The deployment system converts each of the model components into one or more instances that correspond to physical resources.Type: GrantFiled: December 9, 2004Date of Patent: December 26, 2006Assignee: Microsoft CorporationInventors: Galen C.
